HF92F-024D-2C21S High Power Flange Mounted Sealed Relay 24VDC DPDT 30A

The HF92F-024D-2C21S relay from Hongfa is a high-power flange-mounted sealed relay designed for demanding industrial switching applications that require high current handling, strong isolation, and long-term reliability. It is commonly used in power distribution systems, industrial automation, HVAC equipment, and heavy-load control panels.

This relay features a Form 2C (DPDT / double changeover) contact configuration, enabling it to control two independent circuits or provide polarity reversal and interlocking functions in complex control systems. Its 24VDC coil with 350 resistance provides stable and efficient operation in industrial environments where higher control voltage improves noise immunity and system robustness.

With a switching capability of 30A at 250VAC (277VAC max), the HF92F-024D-2C21S is suitable for high-load applications such as motors, compressors, heaters, industrial lighting, and power switching modules. The silver tin oxide contact material provides excellent arc resistance and long operational life under heavy electrical stress.

The relay is constructed with a flange-mounted sealed housing for secure mechanical installation and improved environmental protection. It also features 4 kV dielectric strength and a 3 mm contact gap, ensuring safe isolation between coil and contact circuits in high-voltage switching conditions.
